Struct AudioInput 

pub struct AudioInput {
    pub source_path: PathBuf,
    pub samples: Arc<[f32]>,
    pub sample_rate: u32,
    pub duration_secs: f64,
}

In-memory audio ready for a transcription provider.

Fields

source_path: PathBuf

Original file path when loaded from disk; synthetic label for PCM (pcm://…).

samples: Arc<[f32]>

Mono f32 samples in [-1.0, 1.0], shared to avoid extra copies. For the local provider this must be WHISPER_SAMPLE_RATE.

sample_rate: u32

Sample rate of Self::samples.

duration_secs: f64

Duration in seconds.

Implementations

impl AudioInput

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn from_pcm( samples: impl Into<Arc<[f32]>>, sample_rate: u32, ) -> Result<Self>

Build from pre-decoded mono PCM (e.g. mic capture). No ffmpeg, no disk I/O.

sample_rate must be WHISPER_SAMPLE_RATE (16 kHz). Resample upstream if needed.

pub fn from_pcm_with_limits( samples: impl Into<Arc<[f32]>>, sample_rate: u32, max_duration_secs: f64, max_decoded_bytes: usize, ) -> Result<Self>

Like from_pcm with explicit safety limits.

pub fn from_pcm_slice(samples: &[f32], sample_rate: u32) -> Result<Self>

Copy a slice into a new AudioInput (convenience for mic chunks already at 16 kHz).

Trait Implementations

impl Clone for AudioInput

fn clone(&self) -> AudioInput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AudioInput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
